Chii chinonzi WinRAR delta compression uye maitiro ekuwana zvakanyanya mazviri?

Kana iwe wakambosangana neWinRAR's advanced sarudzo Kana iwe wakambozvibvunza kuti "Delta Compression" ndeyei, iwe wauya kunzvimbo chaiyo. Kuseta uku chikamu cheseti yemaparamita akagadzirirwa kusvina mashoma ekuwedzera mapoinzi ekumanikidza kubva kune chaiyo chaiyo data, asi kushandisa zvisizvo kunogona kudzikisira basa kana kutowedzera mhedzisiro.

Mumitsetse inotevera uchawana tsanangudzo yakajeka uye yakakwana kwazvo pamusoro Chii chinonzi WinRAR delta compression, inoshanda sei, nguva yekuimisa, uye inogara sei? nemamwe ma tweaks senge kutsvaga kwakareba, kutsvaga kwakazara, kana kufanogadzirisa x86 zvinotemerwa. Iwe unozoona zvakare kuti inokwana sei museti yezvisarudzo zvechirongwa (RAR/ZIP fomati, duramazwi, kudzvanya kwakasimba), uye tarisa pa-per-line syntax ye. rairo kune avo vanoda millimeter control.

Chii chaizvo chinonzi delta compression muWinRAR?

WinRAR delta compression ndiyo preprocessing mode iyo inokamura data kuita akawanda single-byte chiteshi uye inochengeta misiyano (deltas) pakati pawo pachinzvimbo chetsika dzakakwana. Izvi zvinonyanya kushanda mumafaira ane zvimiro zvinodzokororwa uye mapatani akafanana, semamwe matafura edata kana hova uko ukoshi hunochinja zvishoma pakati pezvinzvimbo zvakatevedzana.

Mukuita, nzira iyi inobvumira iyo huru compression algorithm kuwana redundancies zviri nyore, kuderedza inooneka entropy uye kuvandudza compression ratioIzvo hazviwanzo kuunza mabhenefiti, asi kana iyo data inokodzera iyo mbiri (matafura, manhamba zvimiro, mamwe akateedzana), inogona kuita mutsauko unooneka.

Izvo zvakakosha kuti usakanganise iyi pfungwa neHTTP "Delta Encoding," nzira yekufambisa inotumira chete shanduko dzine chekuita neshanduro yapfuura yechishandiso; Kunyangwe vachigovana zita rekuti "delta", vanoteedza zvinangwa zvakasiyana. uye kushanda pamatanho akasiyana zvachose.

Mashandiro ainoita: chiteshi uye byte-by-byte mutsauko

Kana delta compression ikagoneswa, WinRAR inobvisa rukova mukati nzira dzakawanda dzeimwe byte uye inoverengera mutsauko pakati pezvinhu zvinoenderana mukati megwara iroro. Fungidzira tafura ine makoramu anodzokorora: iyo delta "inofuratira" shanduko kuitira kuti iyo huru compressor (LZ uye yakafanana) iwane kudzokorora kwakareba.

Iyo delta compression parameter inobvumidza iwe kusarudza iyo nhamba yezviteshi, pakati pe1 ne31Nhamba huru yematanho inogona kubatsira neakakura zvimiro kana data ine yakatarwa periodicity, kunyangwe kuwedzera machanera pasina maitiro anogona kusapa kuvandudzwa uye anogona kuwedzera. el tiempo Of compression.

Ziva kuti izvi preprocessing zvine musoro kune data ine kutsamira kwenzvimbo uye maitiro akajairika; Mune yakatomanikidzwa kana yakanyanya kurongeka data hauone mabhenefiti, uye iwe unogona kunyange kuranga kumhanya.

Kwainobatidzwa uye nemamwe mamodhi ainogarisana

Mune graphical interface, delta compression inoonekwa mukati meiyo Sarudzo dzepamberi dzeRAR/RAR5 fomati, pamwe chete nezvimwe zvinhu zvakaita sekutsvaga-refu-renji, kutsvaga-kupedza, uye preprocessing ye x86 executables. Izvi hazviwanikwe muZIP.

Pamutsara wekuraira, inodzorwa neiyo modifier -mc, ane syntax inoshanduka: -mc[canales][modo][+ o -]. Nenzira iyi, unogona kutsanangura kuti mangani machaneli ekushandisa (akakodzera chete kune delta) uye kuti ndeipi modhi yekushandisa.

Available modes anosanganisira D (delta), E (x86 executables), L (kutsvagisa kwenguva refu), uye X (kutsvagisa kwakanyanya)MuRAR 5.0 fomati, kuenderana kunogumira kuD uye E; L uye X hazvitsigirwe pasi pechigadziko ichocho.

Command line syntax (-mc): zviratidzo uye paramita

Iyo -mc switch inogamuchira akati wandei masanganiswa akakodzera kugona kana iwe uchida kudzora yakaderera-level compression; chiratidzo chiri kumagumo chinogadzirisa chiyero: "+" inoshandisa algorithm yakasarudzwa kune data rese, uye "-" inodzima zvachose. Kana iwe ukasataura chiratidzo, RAR inozvisarudzira zvinoenderana nerudzi rwe data uye nzira yekumanikidza.

Mienzaniso inoshanda: -mcD+ inomanikidza delta compression, nepo -mc- inodzima mamodhi ese (delta, x86, kureba, uye inopedza). Paunenge uchishandisa delta, unogona kutsanangura chiteshi (1–31) pakarepo mushure me-mc: semuenzaniso, -mc31D+ Ini ndaizoedza kushandisa 31 chiteshi nekumanikidzwa delta.

Muenzaniso wakazara wakatorwa kubva murubatsiro rwekirasi unoratidza maitiro ekuita kuti ashande nesimba, duramazwi rakakura, uye kutsvaga kwakazara pamuunganidzwa wezvinyorwa: WinRAR a -s -md1g -mcx texts *.txt. Pano, "-x" mu -mcx inokumbira kutsvaga kwakaperera.

Kutsvaga Kwakareba Kutsvaga uye Kudyidzana kwayo

Basa re kutsvaga kwenguva refu Inomisikidza algorithm inoona mabhuru makuru, kure, anodzokororwa mukati merukova. Izvi zvinogona kuvandudza ese ari maviri compression reshiyo uye, dzimwe nguva, kumhanya kune yakanyanya kudhindwa data (semuenzaniso, zvinyorwa zvakakura), pamutengo wekuwedzera ndangariro kushandiswa panguva yekumanikidza.

Iyi modhi inogona kushandiswa ne compression nzira kubva kubva "Kutsanya" kusvika "Zvirinani" (yakada kuenzana ne -m2..-m5) uye inofuratirwa pakukurumidza kugadzirisa ("Kukurumidza Kwazvo" kana -m1). Izvi zvinonyanya kukosha kana uchishanda nemaduramazwi makuru.

Nemaduramazwi akakura kudarika 4 GB, kutsvaga kwenguva refu activates otomatiki nekuti zvakakosha kutora mukana weiyo saizi; zvichienderana neshanduro uye vhezheni, haugone kuidzima, kunyangwe paine switch (-mcl+ / -mcl-) kubva kumutsara wekuraira kuimanikidza kana kuidzima.

Kutsvaga kwakazara: kunobhadhara rinhi?

Kurongwa kwe tsvaga yakazara Zvinotora kutariswa kwemechi kusvika kune yakanyanyisa: inoongorora zvakadzama mukutsvaga mapatani, ayo anogona kupa diki kudzvanya kuvandudzwa pane yakanyanya kudhindwa data. Kutengeserana kwakajeka: kunonoka.

Kunyatsoshanda, inoda kutsvaga kwenguva refuMuchokwadi, WinRAR inoimisa zvachose kana ukasarudza inopedza modhi. Kana nguva isiri nyaya uye dhatabheti rakakodzera, kadhi raunogona kutamba.

Kudzvanya Intel x86 executables

WinRAR inosanganisira chaiyo preprocessor ye86 uye 32 bit x64 binaries, iyo inovandudza kudzvanywa kwezvinoitwa nekuda kweshanduko dzinoita kuti mamwe macode maumbirwo ave anofanotaurwa. Pamutsara wekuraira, inosarudzwa ne "E" modhi mukati me -mc pachayo.

Kufanana nedelta, iyi sefa haisi yemashiripiti kana yepasi rose: Izvi zvinobatsira kana zvirimo zviri chaizvo x86 executable kodhi; kana iwe ukaishandisa kune imwe data, usatarisira chero kuwana, uye iwe unogona kuona imwe nguva yekugadzirisa.

Kudzvinyirira nzira uye mazinga: kubva ku "Kuchengeta" kuenda ku "Best"

Pasinei nepamusoro pepreprocessors, WinRAR inopa akati wandei pasi rose compression nzira: "Kuchengeta" (hapana kumanikidza), "Kukurumidza," "Kukurumidza," "Zvakajairika," "Zvakanaka," uye "Zvakanakisa." Mazinga epamusoro anoreva kuwedzera kudzvinyirira uye nguva yakareba yekuchengetedza.

Kana iwe uchitsvaga chiyero chekushandisa kwemazuva ese (email zvakabatanidzwa, diki kuendesa), "Zvakajairika" kazhinji ndiyo inonzwisisika sarudzo"Kukurumidza" kwakanakira ma backups enguva dzose uko nguva iri musimboti, uye "Yakanakisa" yakanakira kana saizi yekupedzisira iri pamberi (kugovera internet, kuchengetedza).

Rangarira kuti kana ukasarudza ZIP, mazhinji eaya epamberi preprocessors Hazvisi zvinofambikaKuti uwane zvakanyanya kubva pazviri, shanda muRAR kana RAR5.

Saizi yeduramazwi: ndangariro, kumhanya, uye chaiyo-yepasirese kubatsirwa

Duramazwi inzvimbo yendangariro inoshandiswa nealgorithm tsvaga uye shandura maitiro akadzokororwaIyo yakakura duramazwi, iyo inowedzera mamiriro uye inogona kuita zvirinani kutsikirira, kunyanya kune makuru mafaera uye mune yakasimba modhi.

Semutungamiri mukuru, WinRAR's own zvinyorwa zvinoratidza 4 MB yeRAR uye 32 MB yeRAR5 sezvine musoro default values. Kubva ipapo, unogona kuiwedzera kana mudziyo wako uye mamiriro ezvinhu achizvibvumidza, uchiziva kuti compression ichanonoka uye inopedza imwe ndangariro kana uchimanikidza (kwete decompressing).

Rangarira kuti mamwe mabasa akadai sekutsvaga kureba kuwana kukosha nemaduramazwi makuru; neinopfuura 4 GB, WinRAR inowanzoita kuti iite otomatiki nekuda kwekudikanwa kwehunyanzvi.

Kutsikirira kwakasimba: kuti chii, zvakanakira, kukanganisa, uye nguva yekuishandisa

Iyo yakasimba faira inobata akawanda mafaera seimwe. imwe inoenderera mberi yedataIzvi zvinobvumira kuona kudzokororwa pakati pemafaira akasiyana (semuenzaniso, akawanda madiki uye akafanana mafaera) uye zvakanyanya kunatsiridza mazinga ekumanikidza. Ichi chinhu chakasarudzika cheRAR fomati; ZIP haigoni kusimba.

Izvo zvisingabatsiri zvine basa: kubvisa faira rimwe chete kubva pakati, WinRAR inofanirwa kugadzirisa zvese zviri pamusoro, kuitira kuti kudhonza kunononoka. Zvakare, kana chikamu cheiyo yakasimba faira yakakuvadzwa, mafaera ari pazasi payo anogona kusasvikika, saka ipfungwa yakanaka kugonesa kudzoreredza matanda pane isina kuvimbika midhiya.

Kana yakanakira: kana iyo faira isina kuvandudzwa kazhinji, kana haufanire kugara uchibvisa zvidimbu zvisina kusununguka, uye kana chiyero chekumanikidza chichipfuura kudzvanya uye nekumhanyisa kumhanya.

By default, WinRAR kazhinji ronga mafaera nekuwedzera kuvandudza yakasimba mode performance. Unogona kudzima odha iyi ne -DS kana kutsanangura yako neiyo yakakosha faira rarfiles.lst. Mavhoriyamu uye SFX (yega-yekubvisa) anogona zvakare kusimba.

Ndeapi marudzi emafaira akamanikidzwa (uye ndeapi asiri)

Iko hakuna vimbiso yekumisikidzwa kwakagadziriswa. Imwe neimwe faira inyika: Pane zviri mukati zvinogona kudzikiswa neinopfuura 90% uye zvimwe zvishoma zvishoma, kana kutokura zvishoma nekuda kwepamusoro pemudziyo.

Iwo atove akatsikirirwa (ZIP, 7z, RAR, BZip2…) kana mafomati ane compression yemukati senge. JPEG/PNG/GIF, MP3/WMA, AVI/MPG/WMV vhidhiyo uye zvinyorwa zveHofisi zvemazuva ano (DOCX/XLSX, nezvimwewo) hazviwanzo kuvandudza; edza kuzvichengeta ("Kuchengeta") kana kuabatanidza zvakasimba nemamwe akafanana kana iwe uchitsvaga kurongeka kwete saizi.

Kwaunohwina: plain text, CSV, JSON, source code, logs uye kazhinji yakawandisa data. Ndipo panopenya mafirita (delta, x86), maduramazwi, uye kudzvanya kwakasimba.

Delta uye mamwe mafirita ekare "multimedia".

MuWinRAR yenhoroondo yepamusoro zvigadziriso iwe uchaona mareferensi kumaprofiles akadai "Chinyorwa" (kufanotaura), "Inzwi" (migero), "Rudzi Rwechokwadi" Iko kugona kugonesa 86/32-bit x64 uye delta compression yave kuwanikwa. Aya ndiwo maitiro ekugadzirisa akagadzirirwa kugadzirisa kuyerera kwedata zvichienderana nerudzi rwe data.

Semuenzaniso, sarudza nzira dzakakwirira (kusvika ku31) mu "Sound" nzizi kana kumanikidza delta mumatafura kunogona kubatsira, asi zvakakosha kuyerwa: kushandisa mafirita zvisina tsarukano kunogona kuderedza kushanda pasina kupa kuwedzera kudzvanywa.

Uzivi hwakafanana nekugara nguva dzose: Ziva pateni uye shandisa sefa yakakodzeraKana zvisina kujeka, rega WinRAR isarudze otomatiki uye ongorora mhedzisiro nemuenzaniso.

RAR vs. ZIP: Sei Sarudza Imwe kana Imwe

WinRAR inokutendera iwe kugadzira zvinyorwa RAR (kusanganisira RAR5) uye ZIP.ZIP ikadhi remusango rinoshandiswa nevakawanda, rinobatsira kana usingazive kuti ndeupi chirongwa chichashandiswa nemugamuchiri kudzikisa. Asi kana iwe uchida kuita kwakanyanya uye kuwana kune ese marongero, RAR ndiyo inokurudzirwa sarudzo.

MuZIP, huwandu hwe preprocessed uye tricks (delta, x86, tsvakiridzo dzepamusoro) idiki zvikuruKudzvanya maduramazwi makuru, yakasimba modhi, uye mafirita, shanda neRAR/RAR5 pese pazvinogoneka.

Maitiro akanaka ekushandisa delta compression

Ongorora zvirimo: kana zvirizvo matafura, nhamba yedata, nhevedzano ine shanduko dzakatsetseka kana kudzokorora zvimiro, edza delta yekuongorora. Kana yatova compressed media, chengetedza.

Tanga neiyo otomatiki: rega WinRAR isarudze uyezve enzanisa simba vs. otomatiki pane subset yemafaira. Kana iyo saizi yekuvandudza iri padiki uye nguva ichiwedzera, hazvina kukosha.

Synergies: Delta inoshanda zvakanaka nayo yakasimba modhi uye ane rupo maduramazwi kana iyo dataset ichitendera. Mumafaira akasanganiswa, patsanura nemhando mumavhoriyamu akasiyana kana shandisa kurongedza kwekuwedzera.

Muganho wechiteshi: usaise zviteshi nekuda kwekurodha. Muedzo 4–8, 16 uye 31 kana iwe uchifungidzira periodicity, asi mira kana purofiti yakamira.

Graphical interface vs. command line

Kana iwe ukashanda ne "Archive zita uye parameters" dialog, sarudza RAR/RAR5 fomati, nzira (kubva "Kuchengeta" kusvika "Yakanakisa"), duramazwi, uye mune yepamusoro tab, activate kana kusiya pane otomatiki delta, x86, kureba, uye inopedza modes. Kuti uwane yakasimba, sarudza "Gadzira yakasimba archive."

MuCLI, sanganisa switch: -m5 kune nzira yakanakisa, -s kune yakasimba, -md yeduramazwi (semuenzaniso, -md64m), -mcD+ kumanikidza delta, -mcl+ kwenguva refu uye -mcx kune inopedza (inogonesa yakasarudzika kureba). Gadzirisa zvichienderana nemiedzo.

Rangarira kuti muRAR5, D naE chete ndivo vanobvumirwa mukati -mc; kana ukaedza L kana X mune iyo fomati, chishandiso chinogona kufuratira marongero kana kukupa yambiro.

Tarisiro yechokwadi uye kuyerwa

Hapana anogona kuvimbisa "kugara uchimanikidza X%". Mitemo yemukatiPane zviitiko zvekucheka kunoshamisa, uye kumwe kwaunongowana rutsigiro. Izvo zvaunogona kudzora ndeye huwandu hwesarudzo uye nguva yaunoda kuisa mari.

Nzira ine musoro: gadzira a default compression profile neako aunofarira marongero (RAR5, yakasimba kana iripo, "Yakanaka" kana "Zvirinani" nzira, inonzwisisika duramazwi) uye kune chaiwo mitoro (semuenzaniso tabular) batidza delta uye enzanisa nemuenzaniso.

Kana iwe ukagovera kune wechitatu mapato, yeuka kuenderana: ZIP inovimbisa kuvhurwa kwepasirese; RAR/RAR5 inoda maturusi anoenderana asi inokupa mubayiro nechiyero chiri nani uye kutonga kwakawanda.
